Our invention relates to improvements in magazine guns. It relatesparticularly to an auxiliary magazine adapted for releasable attachmentto the gun stock of a magazine gun of usual type, whereby a largelyincreased number of shells may be supplied to the gun over what isusually stored in the usual magazine thereof.

One of the objects of our invention is to provide a magazine gun ofusual type provided with novel means by which it may be used with theusual magazine equipment, or with a novel auxiliarly magazine which issimple in construction, cheap, durable, not likely to get out of order,which may be easily attached to or detached from the gun stock, which iseasily and quickly operated, and which is reliable in its operation.

The novel features of our invention are hereinafter fully described andclaimed.

In a the accompanying drawings, which illustrate the preferredembodiment-of our invention,

port 9.

' Fig. 10 is an enlarged section on the line 10-1O of Fig. 6.

Similar reference characters designate similar parts in the differentviews.

1 designates the usual gun stock having therein the usual magazine tube2 adapted to receive therein the usual tubular container 3 in which ismounted the usual coil spring 4,

which is adapted to feed shells 5 forwardly.

2, which opening, designated by 8, is closed a by the container 3, whenthe latter is inserted in the tube 2, as shown in Fig. 8.

The notch 7 is adapted to have removably fitted therein a supportcomprising a circular member 9, when the container 3 is re-.

moved from the tube 2, which member 9 is a part of our improvedauxiliary magazine.

The periphery of the support 9 has attached to it a plate 10 having alateral notch 11 adapted to receive a securing pin 12 mounted in theunder side of the stock 1.

' The support 9 on its inner side is provided with an involutespiralgroove in which is fitted a spiral metal strip 13, which forms a shellreceiving conduit, the outer end of,

which terminates in a curved tube ll'WhiCh forms a discharge nozzle, theouter endof which is adapted for insertion intothe opening 8 of the tube2, Figs. 2 and 3.

hells 5 are inserted in the conduit in the channel 15 formed between thecoils of the strip 13 To feed the shells forwardly through the channel15 and nozzle 14 into the tube 2 and thence into the breech 6, thefollowing described mechanism is provided.

A circular revoluble cover member 16 having extending therethrough anaxial pin 17 covers the channel 15 and a part of the nozzle 14. The pin17 is mounted in a central bearing tube 18 in the support 9, said pinhaving an annular shoulder 19 which bears against the tube 18. One endof the pin 17 is threaded and has fitted on it a nut 20 which bearsagainst the outer end of the tube 18, thus releasably anchoring'the pin17 in the supis provided consisting in a plate 25 having one end pivotedto a pin 26 mounted in the outer side of the revoluble member 16'. Theother end of the plate 25 is provided with a transverse hole in which isslidably mounted a pin 27 which is adapted to extend into the channel15, and which is adapted forlateral travel in a slot 28, which extendsin a curve inwardly from the periphery of the member 16. V

For normally forcing the pin 27 inwardly, itisencircled by a coil spring29, 6, one end of which bears against the inner side of the plate 25,and the other end of which bears against a pin 30 in the pin 27.

The inner end of the pin 27 has mounted on it a friction roller 31 whichis adapted to bear against the rear end of the rear shell 5 in thechannel 15. By pulling outwardly the pin27, it and the roller 31 arewithdrawn out of the channel 15 to enable the follower plate 25beingswung laterally, so as to bring the pin 27 from the outer coil of theconduit channel 15 to the inner coil thereof.

The revoluble cover member 16, in addition to its functionof coveringone side of the conduit channel 15. serves as a support for the springbarrel 21 and the follower roller 31 and its supporting means, and as ameans for winding the spiral spring 22; which revolves the cover memberand the parts carried thereby.

Asthe cover member 16 is removable. the spiral channel 15 can be filledwith shells without having to detach the magazine from the gun.

hen the auxiliary magazine is tobe used, the container tube 3 and itscoil springd are withdrawn from the tube 2, and inserted in a receptaclecomprising a hole 32. extending inwardly from the end of the stock 1,Figs. 2 and 8. In the outer portion of the 1101332 is a tube 33 throughwhich extends the tube 3, the latter has in outwardly extending pin 34:which. wherrthe tube 3 is turned, enters a notch 35 in 'the tube 33,Figs. 2 and 9; The tube 2 is alsozprovided with a notch 36 for receivingthe pin 34.

Toreleasably hold the pin 27 retracted, it has through it pin 37 adaptedtdrest on the outer end of a boss 38 on the plate 25, said boss having aslot 39 adapted to receive the pin 37. when the pin 27 is turned,thereby permitting the spring 29- to force the pin 27 into the conduitchannel 15.

In the operation of the gun with the auxiliary magazine, the support 9is attached, as described to the stock 1, the container tube 3 havingbeen withdrawn, and the curved nozzle let inserted into the opening 8.The follow-er plate 25 is swung in the slot 28 to a position in whichthe pin 27 can enter the channel 15 at the inner end thereof.

The channel 15 is then filled with shells 5, the rear one being againstthe roller 31' of the follower pin 27. The revoluble member 16 is thenmounted on the channel strip, or

rather over the same, and the pin 17 is inserted through the bearingtube 18 and the nut 20 is mounted on the pin 17. The loop 23 isa'lsofitted over the pin 24, after which the member 16. is revolvedclockwise, as viewed in Fig, 2,. thus winding the spring 22. The pin 27is in the channelv 15 so that, when the member 16 isreleased, the spring22 will revolve the member 16 counter clockwise, as viewed in Fig. 2,thus feeding the. shells 5 out through the nozzle 14: into the tube 2,asfast as the gun is firedr The follower pin 27 will travel in thechannel 1 5 to the nozzle 14.

When it is desired to use the gun. without the auxiliary magazine, thelatter is detached from. the stock. 1, and the spring container tube3and. its spring 1 are'reinserted into the tube 2.
